i p present invention relatesto shoes, and more particularly'to an improvedgmethod-of lasting the toe portion ofxshoes. 1' y y In Patent No. 1,602,368, issued October fi, [1926,I1have described and'claimed" an Jim provedjmethodof making shoes soasito pro duceian improved McKay ty'pelo'f shoe that i has allthed'esirable features of a McKay shoe as regards strength of structure While also having the advantages of ayweltashoe asre gards flexibility and, in the product on of such shoe, I utilizethevusual and ordinary component parts of the ordinary Iupper, the. ordinaryinsole, and the ordinary outsole.

"16 In Patent No. 1,572,042, issued February 9,

1926, I have described and claimed animprovedjmethod of making shoes whereby there is produced an improved shoe of the McKay .typeand in theconstructionof which 5 20 Iemploy a novel formof combined outsole and insole as described in Patent No. 1,600,019, Sept. 14:, 1926. The present invention relates to an improved process of lasting the toe portion of shoes, which v method 5 is particularly capable of beingupracticed ontaekless McKay shoes, whether the structures thereof include the ordinary "insole and outsole or the novel form of combined insoleand outsole such as that re.

One of the objects ofthis inyention is to I provide amethod of-lasting and securingthe upper around the toe of a shoe, whereby the upper will not only be closely conformedto the last, but in which the presence of tacks in the finishedfshoe is obviated, especially I around-thetoe.-

- Another jobject is to provide, a method whereby the, operations may be performed Anotherobje'ct is tojprovide a m lasting and tacking, whieh'yis particularly applicable for coordination with the methods described in the. patentsreferred to, whereby the entire forepart, including the too as well 1 i as 'thejball and shank, will not only be conformed to i -the" last, but in which the prestially obviated,

' ence of tacksiin thefinished shoe issubstan- Further ob"ects*will app'ear' froni the de- '7 i tail description, taken in connection withthe mompahying d aw n v tion.

Generally stated, in accordance, with vthis invention," the upper is so. lasted around the toe asto conform closely to the last this is accomplished, in accordance with one embodiment, by wiping theupper over the last and moreparticularly over an insoleipart on the last around the toe, as by moving wipers over. the last and insole part and engaging the upperisubstantially continuously there along. An outsole part is then laid, on the part of the upper so lastedyand temporarily tacked thereto-while the upper is held" under tension due to the Wiping; this is accomplished, in accordance withjoneembodiment,

by inserting temporary lasting-tacks through the outsole part and into thelasted upper-at points defined by slots or recesses in the wipers and whilethe latter are in Wiping ,rela-fl The sole and upper are then retained in assembled relation and in closeconformthat the forepart has been lasted as described I 1ity to the last; the wiping means can then be withdrawn while the parts are, sov'retained.

in the patents referred to and the parts permanently secured together, as by seaming or stitching through the sole andupper, and the I lasting tacks withdrawn, all as described in the patents referred to. There 'isthus produced. a shoe which is not onlysubstantially free; of tacks, especially around the toe, but which conforms closely to the last on which it isma de. i I i i i H i In practicing myimproved method, I pref era'bly take the shoe:f(after one of the last.-

ing operations, as described. in one or the surplli s lining and box toe'material, and re -last the shoe on a bedmachine by means I the otherof said patents) and last the toe of a specially formed toe Wiper; and then tack through the outsole,;upper. andinto the insole whileuthe upper is held i n-lasting position under tension due to the wiping, and then completing the construction of the shoe by" withdrawing the lasting device and, sew

ingthe shoe, etc.

1 Inxthe ZIQCOIIIPELIlYlHg drawing-5 I have shown, d agrammatlcally, views of a shoe 11 lustrating' theno'vel method of lasting the toe portionthereof andin the drawing. v a

June 15, 1926. The upper 12 is placed onthe last 10 and by means of the methods de' away.

Referring to the drawing, 10 designates a last 011 which may be temporarilysecured the usual and ordinary form of insole 11. The last with the insolein position'thereon is placed in a lasting machinesuch, for example, as that shown in Patent No. 1,588,916, issued scribed and claimed in said Patents Nos. 1,602,368 or 1,572,042 such upper is lasted to the insole and held by temporary lasting tacks or by means of the wipers employed in the lasting operation. The box toe is placed in position on the shoe structure, the upper is lasted thereover around the toe and into posit-ion on the insole, and the lasted members temporarily fastened with wire, and after the box has become set, the wire is moved and the surplus lining and box toe material is cut The shoe structure is now re-lasted on a bed machine having a. special form of tee wiper13 provided with a plurality of slots or recesses 14, as shown; While the toe portion of the upper is held in position by means of the slotted wiper blades 13, the outsole 15 is placed in position, laid on the lasted part,

and the tacks 16 are driven through the outsole, upper, and into the insole, as shownin F ig. 2, while the upper is under tension due to the'wiping. The last 10 is now withdrawn from the shoe structure which can then be processed in the usual manner to complete the same.

My improved method may be utilized on shoe structures having the usual and ordinary type of insole 11 and outsole 15 or on shoes inwhich there is utilizeda special form of combined insole and outsole, such asis described in Patentv No. 1,572,042, above referred to. The'resulting shoe is a McKay shoe, but is absolutely tackless and therefore extremely flexible, and as the lasting fastenings in the ordinary MeKay shoe add nothing to the strength of the structure after the sewing operation and only serve to stiffen the shoe and frequently work upward through the insole into the foot of the wearer, the shoe produced by my improved method is a decided improvement overthe shoes of this type in the prior art. The resulting shoes have all the advantages of the McKay type of shoe as regards strength of structure and all the advantages of a welt shoe as regards flexibility.

Vhile I have specifically described a procedure in which the operations are performed on a shoe having a certain construction, it will be understood that the same is merely illustrative of one embodiment of this in vention; for this invention, as far. as this method and procedure are concerned, is applicable, in many cases, to other types of shoes. It will furthermore be understood that certain features, steps and subcombinations are of utility and may be employed with out reference to other features and steps; that is contemplated by and. is within the scope of the appended claims. Itv is further obvious that various changes may be made in the details of procedure, within the scope 75, of the appended claims, without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the details described and/or'shown.

Having thus described the invention, what is claimed is:

1. The improved process of lasting the toeportion of shoes of the McKay type which consists in placing a box toe in position on a 8 shoe structure, lasting an upper thereover and into position on an insole, temporarily fastening the lasted members with Wire, removing the wire after the box has become set. 7 cutting away any'surplus lining and box toe material, re-lasting the toe portion, holding the upper in position, placing an outsole in position and tacking through the outsole, upper and into the insole.

2; In the art of making shoes, the process comprising, wiping an upper over a last 7 around the toe, laying the toe part ofa sole on rily tacking the sole part to the lasted part of the upper around thetoe'while the latter is held under tension due to the wiping.

3. In the art of making shoes, the process comprising, wiping an upper over a last around the toe, laying the toe part of a sole on the part of the upper so lasted and inserting 5 tacks through the sole part and into the lasted part of the upper around the toe.

In the art of making shoes, the process compr1s1ng, wiping an upper over an insole part on a last around the toe, laying an outsole part on the part of the upper so lasted and taekingthe outsole part to the lasted part of the upper around the toe while the latter is held under tension due to the wiping.

5. In the art of making shoes, the process comprlsing, wiping an upper over an insole parton alast around the toe, laying an outsole part on the part of the upper so lasted and inserting tacks through the sole part and into the lasted part ofthe upper around the toe.

6. In the art of making shoes, the process comprising, wiping an upper over a last around the toe. laying a sole part over the wipers and on the part of the upper so lasted, temporarily tacking the sole part to the lasted part of the upper while the latter is held by the wiping means and withdrawing the wiping means after such tacking.
